Quizplus · Accepted Answer

Work done is defined as the force applied to an object times the distance the object moves in the direction of the force, which is the same for both weightlifters since they lift the same weight to the same height. Power is defined as work done over time. Since weightlifter 2 takes longer to lift the weight, they use less power.
